-The gperf issue at https://savannah.gnu.org/bugs/index.php?53029
-has been resolved as of the 3.2 release, and not only is the
-/*FALLTHROUGH*/ comment replacement no longer needed, it now
-breaks the build with "error: fallthrough annotation does not
-directly precede switch label". Only do the edit for 3.1.
